Abstract
A high-speed/large-scale architecture, 3D Micro Optical Switching System (3D-MOSS), is proposed. A switching network is divided into sub-network blocks, followed by stacking them to construct a multi-layer structure. The inter-block connection is replaced with short-distance vertical optical wiring, that is, optical z-connection. 3D-MOSS, in contrast with conventional planar structures, reduces waveguide cross points, wiring length, and system size. Expected applications are Switching for Fiber Communications, Reconfigurable 3D Micro Optoelectronic System, and so on. 3D-MOSS consists of OE-films, in which thin-film high-speed micro optical switches are embedded. BPM calculation shows that Variable Well Optical Integrated Circuit (VWOIC), with matrix rectangular electrodes or prism-shaped electrodes on an electro-optic slab waveguide, is viable for the optical switch. BPM/FDTD coupled simulation demonstrates an optical z-connection with 2dB loss in a 4-micrometers -width-waveguide- based network. Resource/cost-saving heterogeneous device integration process, SORT, is briefly described.
